The invention discloses an electric cooker capable of automatically controlling input power. An electric cooker cover is designed into double-layer stainless steel, and a layer of cotton is clamped between stainless steel; both the cooker cover and an inner cooker are designed into six concave-convex interphase wiredrawn edges; an annular cowheel rubber tube is arranged in the cooker cover; the cooker cover and the inner cooker are closed; and when cooking, the rubber tube expands to ensure that hot air in the cooker can not escape out of the cooker. On the basis of the common electric cooker circuit, a thermistor, a charging and discharging capacitor, a bilateral diode, a quick fuse wire and a bi-directional triode thyristor are additionally arranged to control the circuit of a heating element. When temperature in the cooker reaches the set temperature, the resistance of the thermistor quickly increases to prolong charging time, thus greatly shortening the conducting time of the heating element, automatically reducing the input power, and achieving the purposes of automatically adjusting consumption power and saving electricity energy to the utmost.
Description
technical field [0001] The invention relates to a kitchen device for cooking, stewing and cooking, in particular to an electric rice cooker capable of saving a large amount of electric energy. Background technique [0002] At present, in the known electric cooker, after the water in the pot boils, it is still heated with the high power at the beginning, and the heat is dissipated from the pot cover and the pot body, which wastes a large amount of electric energy and also forms a part of the greenhouse effect. Contents of the invention [0003] In order to overcome the problem of wasting a large amount of electric energy in the existing electric rice cooker, the patent of the present invention provides an electric rice cooker, which not only avoids heat loss and saves electric energy, but also makes delicious and nutritious rice, vegetables and soup. [0004] The technical solution adopted by the patent of the present invention to solve its technical problems is: the pot co...
